This textbook shows how to develop the functional requirements of (information) systems. It emphasizes the importance to consider the complete development path of a functional requirement, i.e. not only the individual development steps but also their proper combination and their alignment. The book consists of two parts: Part I presents the underlying theory while Part II contains various illustrative case studies. Part I starts with an introduction to the topic (Chapter 1). Then it explains how to develop functional requirements that represent the conceptual dynamics of an information system (Chapters 2 and 3). Chapters 4 and 5 explain how to model the conceptual statics of an information system. Chapter 6 gives some directions for implementation. Finally, Chapter 7 explains how a ‘technical manager’ can organize and manage the development process. As an illustration of the theory, Part II contains three substantial case studies. The first one (Chapter 8) presents a stepwise development starting from an informal situation sketch via a simple domain model towards a precisely specified, full-fledged conceptual data model, which finally is translated to an SQL database. In the second case study (Chapter 9) the author converts the well-known non-trivial use case Process Sale from Larman into a textual System Sequence Description (SSD). For validation purposes, that textual SSD is subsequently translated into natural language and into a graphical SSD. The third case study (Chapter 10) shows the applicability of the author’s approach to a control system and also illustrates the typical situation that the requirements are constantly changing during development. This book is written for (under)graduate students in software engineering or information systems who want to learn how to carry out adequate problem analysis, to make good system specifications, and/or to understand how to organize and manage an IS-development process. It also targets practitioners who want to improve their problem analysis abilities and/or their ability to make good system specifications. To this end, it includes more than 150 explanatory figures and is accompanied by a Web site which provides additional course material such as slides, additional exercises, solutions to exercises, and the code for the figures used in the book.

9th International Workshop on Foundations of Models and Languages for Data and Objects FoMLaDO/DEMM 2000 Dagstuhl Castle, Germany, September 18-21, 2000 Selected Papers
This book presents a thoroughly refereed selection of papers accepted for the 9th International Workshop on Foundations of Models and Languages for Data and Objects focusing on Database Schema Evolution and Meta-Modeling, FoMLaDO/DEMM 2000, held in Dagstuhl Castle, Germany, in September 2000. The 12 revised full papers presented together with 1 invited survey paper were carefully reviewed and selected for inclusion in this post-proceedings volume. All current aspects of database schema evolution and meta-modeling are addressed.
A fantastic and far-flung compilation of stats, figures, and little-known nuggets about our national pastime An addictive read, sure to spark conversation wherever baseball is spoken, The Baseball Maniacs Almanac is part reference, part trivia, part brain teaser--and absolutely the greatest, most unusual and thorough compendium of baseball stats and facts ever compiled-- all verfied for accuracy by the Baseball Hall of Fame. Renowned sportswriter Bert Sugar, with his trademark tough-guy swagger, presents thousands of fascinating lists, tables, data, and stimulating facts about: Individual players and teams Managers Player relatives The Hall of Fame Annual awards The World Series All-Star Games A list of the all-time statistical leaders for all all the major league teams PLUS: A truly unforgettable "miscellany" section answers such mind-boggling questions as, "Which major-leaguers have palindromic surnames?" and "Which players born under each zodiac sign have hit the most career home runs?

9th International Workshop on Foundations of Models and Languages for Data and Objects FoMLaDO/DEMM 2000 Dagstuhl Castle, Germany, September 18-21, 2000 Selected Papers
The Ninth International Workshop on Foundations of Models and Languages for Data and Objects (FoMLaDO) took place in Dagstuhl Germany, Sept- ber 18{21, 2000. The topic of this workshop was Database schema Evolution and Meta-Modeling; this FoMLaDO Workshop was hence assigned the acronym DEMM 2000. These post-proceedings contain the revised versions of the accepted papers of the DEMM 2000 workshop. Twelve regular papers were accepted for inclusion in the proceedings. The papers address the following issues: { Consistency of evolving concurrent information systems { Adaptive speci cations of technical information systems { Change propagation in schema evolution of object-based systems { Evolving software of a schema evolution system { Logical characterization of schema evolution { Con?ict management in integrated databases { Evolving relation schemas { Conceptual descriptions of adaptive information systems { OQL-extensions for metadata access { Metamodeling of schema evolution { Metrics for conceptual schema evolution { Incremental datawarehouse construction In addition to the regular papers, there is an invited paper by Can Turk ̈ er on schema evolution in SQL99 and (object-)relational databases. Acknowledgements: We wish to thank the program committee members for their work on reviewing the submitted papers. We also wish to thank all a- hors for submitting papers to this workshop. Moreover, all participants of the workshop are thanked for contributing to lively discussions. Thanks also to Elke Rundensteiner, who delivered an invited talk on the SERF-project concerning ?exible database transformations.
